Application filed February 8, 1915.

To all whom it may concern:

. Be it known that we, PAUL CANNELL and \VILLIAM I). CANNELL, citizens of the United States, residing at WVatei-loo, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Apparatus for Vending Liquid; and we do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to apparatus for vending liquids, and consists more particularly in an improved apparatus for vending su'ch liquid as gasolene, designed to be placed at suitable intervals along highways for the convenience of motorists, and which will be inclosed to prevent tam pering or operation by unauthorized persons prior to depositing a proper coin therein.

Our invention is designed to utilize the rack and pinion pumping mechanism, now usually employed to raise gasolene and other liquids from sunken wells or reservoirs; and the invention has for an object to provide an improved coin or check-controlled apparatus for normally locking the pumping mechanism to prevent unauthorized delivery of fluid, and which, on depositing a suitable coin, will release such mechanism and permit pumping of a quantity of gasolene proportional to the denomination of the coin.

Another object of the present invention resides in providing an improved apparatus of the above character including a novel mechanism for compelling ,full strokes of the pump whereby delivery, of the proper amount of gasolene will be'assured, at the same time rendering it impossible to operate the pump on short strokes without'shifting the locking device into engagement there with.

The invention has for a further object to provide means for limiting the strokes of the pump and for adjusting same to secure variable stroke lengths corresponding tothe price per gallon of gasolene. which, as is well known, has a fluctuating value.

\Vith the foregoing and other objects in view the invention consists in the constructions, combinations and arrangements herein described and claimed.

Fig. 2 is an end elevation of the same. Fig. is an enlarged view of the full-stroke mechanism. Fig. 4 is a vertical sectional view of the coin-controlled apparatus, illustrating the pump pinion and rack in dotted lines. Fig. 5 is a transverse section view of the same and showing the pump elements in full lines. Fig. 6 is a top plan view, partly in section, of the coincontrollcd apparatus; and Fig. 7 is an enlarged fragmentary perspective view of the same. I

Referring more particularly to the drawings, and especially to F igs, 1 and 2 thereof, 1 designates a housing erected on the surface above a sunken well or tank 2, containing gasolcneor other liquid to be vended; said housing 1 being constructed to inclose the several mechanisms of the apparatus and prevent fraudulent tampering therewith. In the tank 2 is located the usual pump cylinder 3, wherein reciprocates a alved or other plunger 4, connected to be operated by a piston rod 5 from a rack 6 in mesh with a pinion 7, the same being arranged to be actuated by a crank handle 8 projecting from the housing 1. From the cylinder 3 leads a pipe 9 to a delivery spout 10, from which the gasolene may be collected in buckets, or may be delivered directly,

through a hose to the fuel tank of a motor vehicle. The pumping mechanism is nor mally locked, to preventunauthorized persons operating the same prior to depositing a coin in the machine, by a latch 11, under the control of a coin or check-control apparatus mounted in a casing 12 and secured to the housing 1 in any suitablemanner. The coin-controlled apparatus is more particularly illustrated in Figs. 4 to 7, inclusive. and will be hereinafter referred to in detail.

To insure full strokes of the pump plunger a full-stroke mechanism is provided to engage the pinion 7, and mounted on a frame 13 within the housing 1. Such fullstroke mechanism is more particularly a double acting the iran'ie l3 indiand lorn'ied at its opposite end ind l7 adapted to engage beof the pinion 7, The teeth ouble acting pawl ll are the pinion 7 uheld to a A it Will be understood cul ui that to th il lS in engagement latter will be. permitted wise direction only, as 23'. and while the tooth i7 is n 5? with. the pinion, as shown in nip the pinion 7 will be permitted to rotate in a rourtercloclrwise direction and lock 7 'nst rotation. in the opposite (I ..ne double acting pawl 1% is 'irarvnled with a rearwardly extending arm 19. coupled by a loose joint 20 to a link ill, the opposite end of which latter is conneat-ed. to one arm of a bell crank lever 22 tulrirunierl at one end of the frame 13, as 33. At the opposite end of the with the. pinion, the to rotate in sec n from r indicated at 1 frame l3 is fulcrnined a similar bell crank lever Z-l, con ed to actuate the bell crank .52 through a l eu; liul; 25. The horizontal 1 "in or the bell crank lever 2% extends into the path of projection 26, mounted on the lower end of the rack bar 6, and adapted to he engage-fl the latter on the upward limit of movr .llf. of the rack bar to rock said bell cran 1 lever, andthrough the assoelated links 25 and E21 and the bell crank. shift the tooth 17 of the double acting vl from the position shown in Fig. 1 ll. position shown in Fig. 3, where tooth in in engagement with the ion 3'. The crank handle 8 is thereupon and the pinion 7 rotated in a clocke direction to move the rack 6 down "ardlv and disengage the projection 26 the bell crank lever 2 L At the lowerits travel, the projection. 26 t adapted to engage an arm :riel by the lower end of a rod 28 all; v m inted in a scale bar 29, and held n after adjustment by a set screw l 28 provided at its upper end with a pointer 31 arranged to travel over the sca e '29, whereby the stroke of the rack I to A l u 1 i be regulated in accordance with the prev; ling market price of the liquid to be winded. The scale bar 29 is suspended trom a rod supported from the horizontal arm of the bell crank lever As indicated in dotted lines in Fig. 3, it will be understood that when the rack 6 descends to the lowermost limit of its travel, the projection 26 ounters the arm 27 and moves the rod 28 parts to rockthe bell crank the to-pi: 1'? into engagement inion as shown in Fig. 1; 2' mien may be reversed Bel and sin the j.

referring more particularly to l to '7, inclusive, the apparatus for controlling the operation of the latch 11 contained within a casing 12, above stated; the said using 12 being divided by a partition into two transverse vertical compartments and 35 the former of which is formed with a depressed bottom providing a depository for the coins. The latch ll is slidably mounted in a guide 37, ecured to the housing 1, and is pro. iClQCl with a 3S projecting through a slot 239 formed in the wall of the casing 12 adjacent the housing 1, and resting on the outer tree end of an arm lO fixedly mounted on a rock shalt ll. The arm l0 is normally in the raised position shown in full lines in Figs. -l and 5, where it maintains the latch 11 in engagement with the pinion 7 and ellect-ually blocks the pumping mechanism. 011 the rock shaft ll'are mounted a plurality of iort arms 42, 4.3 and 44, formed each with a slot l5 into vvuich projects a key 46 on. the rock shaft; and whereby the short l2, l3 and H may be actuated individually to impart movement to the rock shalt ll without aliecting the position of the companion arms. '1 he outer ends of the short arms l2, 43 and ll are preterably bifurcated, as shown in Figs. 5 and 7, for receiving the lone ends of toggle levers 4LT, l8 and 3, sus iended from arod 50 mounted transversely in the walls of the compartment The upper members of the toggle levers as illustrated toudvantage in Fig. l, are adapted to normally occupy a position in close contact with the partition 33, and are actuated by the coin carrier. as hereinafter described, to move into the dotted lineposition shown in this ligure and depress the corresponding short arms 42, 4.3 and 4.4 to rock tlie shalt ll and shift the arm 40 to the lower position permitting the latch 11 to drop by gravity and disengage the pinion 7. Each of the upper members of the toggle levers4-7 l8 and 49 isprovided with projections 51 adapted to be engaged by note es 52 provided in latch bars 53, and 55, mounted to swing on a rod 56 and sup ported at their outer ends upon said projections 51. The complemental projections 51. and notches 52 in the several latch bars 53, 54 and 55 operate to maintain the respective toggle levers 47, 48 and l9 in operated position until lifted, by a carriage 57 to disengage the projections and notches and permit the levers to be returned to initial position side of the upper supporting rod 59 for engaging the under sides of the latch bars 53, 54 and for raising the same to disengage the notches 52 thereof with the projections 51 on the several toggle levers. 0n the op posite sine of the upper supporting bar 59 the carriage 57 is formed with a rack 62, adapted to be engaged by a pawl 63 pivoted as indicated at 6i in the compartment 35 of the casing 12 and provided with a pin (35 in proximity t6 its outer free end for engagement by an L-shaped member (56, the same being connected to the arm 49 as indicated at 67 in Fig. 4. The underside of the carriage 57 projects beneath the lower supporting bars 59, and is similarly provided with rack 68 engaged by a weighted pawl 69 pivoted on a bell crank lever 70 mounted in brackets 71, and having its horizontal arm projecting through a slot in the casing wall to be engaged by a lug 72 mounted on the rack 6, and formed with an offset portion 73 for re ceiving the arm 49. The weighted pawl 69 is, at its butt end, provided with a pin 74 engaging through a slot 75 formed in the lower end of a link 79, pivoted at its upper end in the horizontal extension of the Lshaped lever 66.. In the compartment34 of the easing 12 is journaled a shaft 77 on which are mounted a plurality of angular levers 78. supporting at their upper ends a coin carrier 79. The coin carrier 79 is provided with a plurality of com 'iartmenm, sl tted at their upper ends. as indicated at 89, 81 and 82, of different dimensions to accommodate coins of various denominations. In the initial position of the coin carrier 79 as shown in full l nes in Figs. 4 and 7, the coins are n'evcnted from dropping through the compartn'ients therein by means of a bottom 83 secured to the front wall of the casing 12, as indicated at 84. The front and rear walls of the coin carrier are preferably inclined, as illustrated to advantage in Fig. 4, and each compartmcnt thereof is provided with a fraud-preventing device 85, for removing washers; and it is to be understoml that any other well known trawl-preventing device may be employed in conjunction with the present apparatus. The front walls of each of the coin compartments So, 81 and S2 of the coin carrier 79 are. constructed withswinging gates 89, 87 and 88, respectively, provided each with pins or projections 89, 90 and 91. The coin, carrier 79 is exposed, for the insertion of coins, through an opening 92, in the top of the casing 12, as will be seen from an'inspection of Fig. 6, and may be operated by a hand-grasp 93 projecting above the casing, as illustrated, and operating in a slot 94 formed therein. Subsequent to the insertion of the proper coin, the carrier 79 is adapted, through the hand-grasp 93, to be oscillated on the supporting levers 78 to the dotted line position shown in Fig. 4, when the projections 89, 90 and 91 will enter perforations 95 provided in the partition 33, and operate to force the respective toggle levers 47, 48 and 49 into the dotted line position therein shown. here the coin carrier 79 is thus oscillated without previousl inserting a coin therein, the gates 89, 87 and 88 will be moved inwardly Within the compartments 80, 81 and 82, respectively, when the pins 89, 90 and.91 encounter the respective toggle levers 47, i8 and 49, and will be ineffectual to actuate the latter. Upon the deposition of a coin in one of the compartments of the carrier 79, the corresponding swinging gate will be prevented thereby from inward movement, and will consequently actuate the corresponding toggle lever when the coin carrier is swung into actuating position. In the casing 12, above the coin carrier 79, is journaled a shaft 96 whereon are mounted a plurality of levers 97, one for each compartment of the coin carrier 79, and provided with downwardly extending arms 98 in the path of the coin carrier and adapted to be engaged thereby to revolve the levers to force the coins through the bottoms of the compartments, as indicated in dotted lines in Fig. 4.

The machine is adapted to contain a notice of the prevailing market price of the gasolene per gallon, and to this end the top of the casing 12 is provided with an inspection opening 99, to the immediate right of'which is placed a cent mark, indicated at 100. -Within the casing 12 is arranged a number wheel 710i, to which access may be had by the proprietor of the machine for revolving the same to bring the proper number thereon in, registry with the inspection opening 99 and opposite the cont mark 100 to notify purchasers of the prevailing price oftho gasolene, and for which the pum ing mechanism has been set to correspond.

In operation a quarter, half dollar or dollar is inserted in the corresponding slot 80, 81 or 82 of the coin carrier 79, the same assuming the position in the respcctivechin compartment, as indicated in dotted lines in Fig. 4; and it is to he understood that although, for convenience of illustration, .,\\'e have shown the coin box 79 as comprising but three separate compartments, the same may be constructed of any suitable ntun her and the associated parts of the apparatus multiplied accordingly. \Vhen, for instance, a quarter is inserted in the slot of the coin carrier 79, the same takes up a posi' tion between the rear wall of the coin compartment and the swinging gate 86 thereof, preventing the latter from moving into the compartment when the coin carrier is.

pushed rcarwardly by the hand-grasp 93. \Vhcn the purchaser so operates the coin carrier, the pin 89 on the swinging gate 86 of the comnartment 89 .;ill enter its perforation 9:; n the partition 33, and actuate the respectlve toggle lever x7 to move mm the vclo tted ling p psitiqn i GO Vill 'actuz ie tll wlll be held in posltw the 021.11
